Stages in the recovery of feeding following vagotomy in rabbits

Rabbits were either chronically vagotomized or laparotomized (controls) and maintained on free-feeding regimens. In Experiment 1, animals received greens, liquid, and solid foods while recovering. Vagotomized animals showed a recovery syndrome and other alterations in feeding control similar to the lateral hypothalamic syndrome. After an initial anorexia, when the rabbits ate only fresh greens, liquid food (chocolate diet drink) was eaten followed finally by a recovery of solid food consumption. No direct effects on water intake were seen. Once recovered vagotomized animals on solid food ate longer but less frequent meals than did controls. In Experiment 2, vagotomized rabbits showed the pattern of frequent small meals on liquid foods. On solid food, while recovering, the vagotomized rabbit again ate small frequent meals. These results indicate that the vagus nerve participates in meal patterning and appetite and that the effects of vagotomy show temporal changes, probably due to a reorganization of regulative controls. The data also indicate the importance of vagal afferant and efferent information in the control of eating.

Palatability and Nutritive Value of Fresh, Canned, and Frozen Collard Greens1

Abstract Nutritive value present in raw greens may be drastically reduced by methods of preparation, or fresh greens may not be utilized because of the time and labor required in their preparation by working mothers. Collard greens as prepared in the ghetto home require many hr of cooking which destroys all but 8 mg/100g of ascorbic acid. Seasoned, canned, collard greens are equally acceptable but retain only slightly more of the ascorbic acid. Pre-cooked, pre-seasoned, and frozen greens retain approximately 20 mg/100g of ascorbic acid. If produced on a commercial scale, the prepared frozen product could be purchased at a cost lower than raw collard greens at the retail urban market.

Reversal of aminopterin toxicity by water-soluble cupridihydroporphyrins (chloresium).

Ingestion of 2 mg. per kilo per day of water-soluble cupri-chlorophyllins (Chloresium) protected weanling rats on a milk diet from aminopterin toxicity in each of seven experimental series. Similar protection was observed in one series of rats on a standard laboratory diet and in one series on laboratory diet supplemented with fresh greens.

Feeding and breeding of laboratory animals III. Observations on the feeding of guinea-pigs

1. A dry pelleted diet is described which, supplemented with fresh greenstuff, dried cabbage, or ascorbic acid, is highly satisfactory for the growth and maintenance of guinea-pigs.2. No evidence could be found that the pelleted diet alone was deficient in any other factor than vitamin C required by guinea-pigs, fresh greens and dehydrated cabbage being effective because of their high content of this vitamin.3. Vitamin C added to the diet as crystalline ascorbic acid or as present in dried lucerne meal is mostly destroyed by the pelleting process and is further reduced during storage.4. The aim of evolving a dry pelleted stable diet completely adequate for guinea-pigs has not yet been realized.It is a pleasure to acknowledge our indebtedness to Miss M. Olliver, Messrs Chivers & Sons Ltd., who carried out the ascorbic acid determinations and gave us much valuable advice.Our thanks are also due to Roche Products, who gave us the ascorbic acid, to the Director of Messrs Chivers & Sons Ltd. for the generous gift of 1 cwt. of standard dehydrated cabbage, to the Dehydration Division of the Ministry of Food for supplying two samples of sub-standard dehydrated cabbage, and to Mr D. G. Short, senior technician in charge of the animals at the Institute, who prepared the small-scale diets.

Whitehead's Philosophy: Theory of Perception

When the weather is fair, it is the custom of the writer to take a walk across the common which abuts on to his house and garden. This morning he observed the fresh green of the spring grass, and at the same time heard from an adjacent hawthorn bush the cheerful song of the thrush. As he proceeded, the scent of burning brushwood in a clearing near by was smelt. He picked up a stick lying on the grass and used it as a staff. Within a few minutes he had enjoyed sense experience through eyes, ears, nose and hands. In the autumn he hopes to gather from the bushes a handful of blackberries, as he has done in many previous years, and enjoy their luscious taste.

Nutritional glossitis and vitamin B 2 therapy

The successful treatment of six cases of superficial glossitis with synthetic riboflavin is described. The aetiology of nutritional glossitis as ascertainable by therapeutic tests is discussed. Recent analyses reveal that spinach is a rich source of riboflavin. It is therefore of interest that fresh greens are remarkably deficient in the school diets, although regularly provided in the home diet.

Pellagra

IN A SMALL Mexican village, a pueblo of Texas, a modest family lived, laughed, and enjoyed the peaceful tranquillity of their existence as only a Mexican family can. Here, with many of his comrades and amigos, lived Senor Valentin C, his wife, Senora Julia Garcia, and their two niiios, Manuella, a girl of six, and Jose, a boy of four. In the joy of expectancy, the sefiora attempted to forget the chubby brown-eyed ninio she had buried with the good priest's blessing only a few months before. She must make ready to provide suitably for the new baby to come. All winter the sefiora worked and saved. At last all arrangements were made, and even the good God blessed their home. The weather grew milder; Manuella and Jos6 lost their colds; Valentin had steady work; money saved for many months, and hidden carefully, was brought forth; neighboring women came to help; and on a bright March day, little Flora opened her big velvet black eyes. The breeze coming through the open window was laden with the scent of early spring flowers, and thus the Little Flower was named. The family of five lived happily and healthfully, the children sick only occasionally with childhood diseases. As they grew older, all attended the public scho ls where they made average grades, passing regularly and fairly easily. Their diet, like that of their neighbors, consisted chiefly of tortillas (flat cornmeal cakes) and frijoles (beans), with the addition of fresh fruits and vegetables at inte vals. The sefiora, good housewife that she was, saw that her children had milk and fresh greens and fruits as regularly as possible. In 1920 the family migrat to California, Valentin getting work with a railroad company, and continuing to provide steadily for them. In time, Flora entered high school, graduating four years later. In 1939 disaster struck. The good sefiora, after working and providing for her family through the years, and helping Manuella (by this time married, with two children of her own), became too ill to continue, and, at last, died. An abrupt change in the family life followed; no one to guide them, no one to cook for them, no one to plan, no one to supervise. They mer ly drifted. Flora, without utilizing knowledge acquired in the cooking classes of he high school, prepared only the simplest foods possible. Frijoles, mush, bread, and coffee constituted the main fare, with rarely any meat, milk, eggs, or vegetables. She discovered, also, that by eating cereals and nothing else, twice

The effect of riboflavin and the filtrate factor on egg production and hatchability

Abstract does not appear. First page follows. Introduction Numerous investigations(Bethke and Kennard, 1928); (McFarlane, Fulmer, and Jukes, 1930); (Titus, Byerly, and Ellis, 1933)6 have indicated a factor or factors required for hatchability other than the fatsoluble vitamins. The factor or factors seemed associated with some protein concentrates and with such feedstuffs as alfalfa, milk, liver, yeast, and fresh greens. Later work (Halpin, Holmes, and Hart, 1933); (Bethke, Record, and Kennard, 1933); (Heiman, 1935) indicated that vitamin G was the factor responsible. It is now known (Birch, Gyorgy, and Harris, 1935) that the term “vitamin G” as previously used in the literature covered the complex action of several vitamins. (Bethke, Record, and Kennard (1936)) have suggested that riboflavin was the active factor responsible for increased hatchability. On the other hand, (Smith and Branion (1936)) have expressed the opinion that more than one factor in the vitamin-G complex7 is involved in hatchability of eggs.
